APPLICATIAON 'FILED FEB. 14. X907.

UNiTnn erariale JOHN BAKER, OF ASADENA, CALIFORNIA.

Application tiled February 11i, 1907.

To all whom it may concern.'

Be it known that I, JOHN BAKER, a citizen of the United States, residing at asadena,

-in the county of Los Angeles andState Qvention are to provide means for detachably securing the tire tothewhecl which is' simple in construction, economical of manufacture, and whichdoes not depend :torits operation upon boltspscrews, pins, keys, or the like. I am awarethat a' device of this general nature is not generically new, and l. therev` fore. do not clain'i such general type of construction broadly, as my present application relates to an im roveinent in that type oi devices which will hold the tire 'securely in place, even though the tire becomes considerably relaxed.

The accom anying drawings illustrate the invention an referring thereto :-Figure l is a cross section through a tire and a wheel fell'y e%`uipped with one form of the invention. ig. 2 is a plan View oi the locking ring for securing the parts together.

v nates'the inner air -tube of the tirea l designates the felly of the vehicle wheel. to which felly is secured al rim 2, formed preferably of metal and having at one edge a flange 3 a ainst W ich is seated a retaining ring 4: whic interlocks with an enlargement 5 at the inner ed e of the tire-6. 7 desig- The other edge of the rim 2ghas a thick inwardly projectin fla e 8 which abuts against the ed of t e fel y1, the flange 8 being pro-- vi ed with an annular groeve 9, Another retaining ring 4 is mounted on the edge of the rim 2 adjacent the flange 8 andinterloclfs With'the adjacent enlargement oi the tire 6. In,the present drawings .l have shown the retaining rings Il as duplicates of each other and interchangeable.

The retaining ring 4 adjacent the flange 8 is locked in position by a split locking ring 10, shown in detail in Fig. 2, which locking ring is L- shaped in cross section, thus having two annular leaves or flanges at right angles to each other, one of which flanges l is beveled or inclined upon its inner irclnnfcrcntial face and seats in the groove 9ct the rim 2, said seat being correspondingly inclined Specification of `Lett-.ers F'atent.

,outer face shouldered recess in the retaining ring Ll.

locking ring l() has a natural tendency to 63 atented Feb. 23,1909.

Serial No. 357,414.

While the other fiance 12 is formed with its as shown at 14 to contorni to a correspondingly shaped seat or The split close its two ends together as shown in Fig. 2, and to place'it in position engaging in the groeve 9, the retaining ring 4 is ushed toward the center of the rim 2 as indicated indetted lines in Fig. l `until 'the outer edge of the retaining ring t fully clears the groove 9 in rim 2., whereupon the s )lit locking ring 'l0 may be sprung apart'slightly to slip over the cuter diameter of the rim and moved in. until its flange ll registers With- 7:7

the groove 2, 'whereupon the lockingv ring contracts, springing its flange il, into `the groove 9, the ends of the locking ning then closing so that it forms a complete circle.

The retaining ring et is thcnfnoved outward 7? until stopped by the lock ring and the pressure et' the tire holds the retaining ring l outwardly against the locking ring. lt will be noted that in order to release the tire,

it must first be deflated to permit it to be Se 'moved a considerable distance, as indicated by dotted lines, to permit the necessary inward movement oi the retaining ring i to enable the locking ring l() to be withdrawn,l

and therefore a slight yielding of the tire is `insuilicient. to accomplish this releasing functie anddliis feature is one of decided in preventing accidental detachvthe tire. By constructing thev groove :nent or 9 'with an inclined seat and the locking ring-'99 1() with an inclined face'in this manner it is evident that the ring can be inserted or removed with a n ich less inward movement of the retaii'iin ng Llthan Where the retaining ring is w the rim with a groove for receiving it.

What l claim ist" l A rim having a jroove at one edge, the bottom ofthe groove being inclined and extending from the outer edge oi the riln loo inward and downward und the inner Wall extending at an acute angle thereto to the perinbery of the rim., a retaining ring on the rim having a groove in its inner face,' the inner l at a point nearer'tlie outer edge of the rim'' than the inner wall of said groovev and the. other Wall is at right angles thereto, and e split locking ring in said grooves, the inner circumferential face of which is beveled to l provided with a dang@ and o5 Wall 'of which groovel is normally 5.0.3
